Abstract

L'invention concerne des membranes à osmose directe qui comprennent une couche active et une couche mince de support. Un substrat à double couche comprenant une couche dorsale amovible peut permettre de traiter des membranes à osmose directe avec une épaisseur de couche de support réduite sur les chaînes de fabrication existantes.
